IMPROVEMENT IN IMPLEMENTS FOR CAPPING AND UNCAPPING CARTRIDGES.

Specification forming part of Letters Patent No. 220,979, dated October 28, 1879; application filed September 24, 1879.

To all whom it may concern:

Be it known that I, ALBERT D. LAWS, of Bridgeport, Fairfield "county, State of Connecticut, have invented an Improved Device for Capping and Uncapping Cartridges, of

the device, and Fig. 2 a plan View, showing the parts in a different position.

A is the base'pl'ate, supporting a central standard, B, upon which swings a frame, C, having a circular recess, a, adapted to receive the cartridge, as shown in Fig. 1.

The frame is provided with a standard, I), which extends upward into the opening a, concentric with the latter, and is recessed to receive a stem, D, terminating at the upper end in a pin, 0, and resting on the plate A, against which it is pressed by a spring, 0.

The plate A is provided with a curved incline, E, corresponding to the path traveled by the stem D, which is therefore raised when the frame is turned to the position shown in full lines, Fig. 1, and is depressed by the spring when the frame is turned to the position shown in dotted lines, Fig. 1.

To the end of the standard B is pivoted a le ver, F, carrying a double-ended block, G, so arranged as to be brought above the standard 13 when the lever is turned to either position shown in Fig. 1.

One end, 00, of the block G is flat. The other end, Q, is provided with lips a n, adapted to bear on the head of the cartridge on opposite sides of the central recess, 8.

When the frame C is turned to the position shown in dotted lines, Fig. 1, the stem D is thrown down, so that the pin 0 is below the end of the standard I), and cannot interfere with the capping of the cartridge, which is effected by pressing the cap 93 into therecess s by bearing upon the cap with the end 00 of the block G, as shown in dotted lines.

When the frame is turned to the position shown in full lines, Fig. 1, the stem D will be elevated by the incline E, and when the cartridge is passed through the opening a the projecting pin 0 will strike the inside of the cap. On turning the lever Fto the position shown the lips n of the block G will be brought to bear upon the head of the cartridge, and the latter will be forced downward, while the cap retains its position and is detached.

By merely swinging round the frame the cartridge is brought to a position in which a new cap may be applied by means of the lever F, while the dischargepin c is withdrawn, so as to avoid all danger of exploding the cap.

It will be apparent that a threaded stem, D, having a pinion on its end and revolved on turning a frame, C, by contact with a curved rack on the plate A, may be substituted for the springsteni, and that the standard I) may be used without that portion of the frame containin g the opening a. Without therefore confining myself to the precise construction shown,

I claim- 1. The combination of the base A, vertical standard B, frame C, swinging on said standard, and provided with a standard, b, carrying a stem, D, terminating in a discharge-pin, 0, devices for elevating and depressing the stem asthe frame is turned, and reversiblelever F, carrying a block, G, plain at one end and with lips at the other, substantially as set forth.

2. The combination of the frame C, its standard and sliding stem (1, and the base A, provided with an inclined bearing for the stem D, substantially as set forth.

3. The combination of the frame C, tnrnin g on a vertical standard, and its devices for retaining and decapping the cartridge, and the reversible lever F, carrying a block, Gr, adapted to operate on the cap and cartridge at its opposite ends, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT D. LAWS.
